Setup

Install RSpec mode

In emacs, M-x package-install rspec-mode[RET]

Install override code

Add the elisp to your start-up sometime after rspec is loaded. This overrides an interal method of the mode so we can munge the path. Set the options to your liking. I ignore the opts file and bundler to make all this easier on myself.

Install script

In shell, assuming $HOME/bin is in your path:

mv vrspec ~/bin/
chmod +x ~/bin/vrspec

Eval/reload things

Basic Usage

In emacs in a spec file:

C-c , s ; run the spec at point. If on describe/context, will run that set
C-c , v ; run file
C-c , a ; run all specs. Won't work with this setup
C-c , C-h ; see what commands are bound to keys. No warranties expressed or implied.

In result buffer

g ; re-runs
q ; hide buffer
h ; get command list

vrspec

#!/usr/bin/env bash
# This should be in $PATH and executable
dir=`pwd`
dir=${dir#$HOME/dev/}
vm=${dir%/*}
ssh -t $vm "/bin/bash -l -c 'bin/rspec $*'"
